24 Hour Psycho by Douglas Gordan 1993, 35mm film projection/installation. (click on still for a 30 second clip)

24 Hour Psycho (1993), a slowed-down version of Alfred Hitchcock's 1960 film Psycho. A different take on a familiar classic, recognition and repetition, time and memory, complicity and duplicity, authorship and authenticity, darkness and light.

Douglas Gordon in his own words: "24 Hour Psycho, as I see it, is not simply a work of appropriation. It is more like an act of affiliation... it wasn't a straightforward case of abduction. The original work is a masterpiece in its own right, and I've always loved to watch it. ... I wanted to maintain the authorship of Hitchcock so that when an audience would see my 24 Hour Psycho they would think much more about Hitchcock and much less, or not at all, about me...

Realistically, no one can watch the whole of 24 Hour Psycho, which consists of Alfred Hitchcock's film Psycho (1960) slowed down so that a single, continuous viewing lasts for twenty-four hours. While we can experience narrative elements in it (largely through familiarity with the original), the crushing slowness of their unfolding constantly undercuts our expectations, even as it ratchets up the idea of suspense to a level approaching absurdity.

Account of the artist's statement "He [Douglas Gordon] went on to imagine that this ‹someone› might suddenly remember what they had seen earlier that day, later that night; perhaps at around 10 o'clock, ordering drinks in a crowded bar with friends, or somewhere else in the city, perhaps very late at night, just as the 'someone' is undressing to go to bed, they may turn their head to the pillow and start to think about what they had seen that day. He said he thought it would be interesting for that 'someone' to imagine what was happening in the gallery right then, at that moment in time when they have no access to the work".
